Allison Kennedy, organizing director of Neighbor to Neighbor, said her organization abided by all laws governing elections and said affidavits submitted to the Election Commission Monday night are designed to intimidate voters from going to the polls.

“We have been doing work in Worcester since 1996,” Ms. Kennedy said. The group describes itself as a progressive organization of working class, multiracial, and multi-ethnic people working together to build political and economic power.

“We've been going door-to-door since June and educating voters all summer,'' she said. “These attacks are fear-based attacks and quite a desperate attempt by the losing side in a midterm election.”

Desiree Awiszio, volunteer deputy campaign manager for Republican Martin A. Lamb in his failed bid for the 3rd Congressional seat, presented sworn affidavits Monday by poll observers who said Neighbor to Neighbor members accompanied people into voting booths and told them how to vote.

Ms. Kennedy said her organization does accompany voters who request assistance, which is permitted by state law. Some voters ask for help because they have vision problems, have some physical difficulty or are unable to read the ballot, she said.

She said her organization targeted 13 precincts in Worcester and that 117 volunteers were on hand in the city. Neighbor to Neighbor likely was responsible for about 5,000 Worcester voters going to the polls, counting outreach before and on Election Day, she said.

The Election Commission said they will refer the 12 pages of allegations to the secretary of state's office for review.

“The work we do is fully protected by the law, and apparently people made some complaints, but there's no legal basis for any of it,'' Ms. Kennedy said.
